In the title compound, C25H25NO2, the phenyl ring on the 1,3-oxazole ring is disordered over two positions with occupancies of 0.600 (4) and 0.400 (4). The inter­planar angle between these two disordered rings is 77.8 (2)°. There is an intra­molecular O—H⋯N hydrogen bond of moderate strength. In the crystal, C—H⋯π inter­actions interconnect neighbouring molecules. The absolute structure has been derived from the known absolute structure of the reagents.

Comment top

Over the last decade, C2-symmetric chiral oxazoline metal complexes have been recognized as an effective class of chiral catalyst in a variety of transition metal catalyzed asymmetric reactions. Thus, the design and synthesis of new chiral oxazoline ligands has inspired many scientists to work with great efforts (Ghosh et al., 1998, Johnson & Evans, 2000).

The title compound (Fig. 1) is a new oxazoline ligand, (S)-2-methyl-1,1-diphenyl-2-(4-phenyl-4,5-dihydrooxazol-2-yl propan-1-ol), which has been designed as a potential ligand for asymmetric catalysis. It combines diphenyl methyl units and chiral oxazoline ring together with dimethyl methyl malonate.

Fig. 2 shows the packing of the molecules in the title structure.

Peculiarity of the title crystal structure is presence of a disorder which affects one of the phenyl rings which is split into two positions: C20//C21a//C22a//C23a//C24a//C25a and C20//C21b//C22b//C23b//C24b//C25b, the respective occupations of which are 0.600 (4) and 0.400 (4). The interplanar angle of both disordered rings equals to 77.8 (2)°.

There is an intramolecular hydrogen bond O2—H2···N6 of moderate strength in the structure (Tab. 1). (For categorization of the hydrogen bonds, see Gilli & Gilli, 2009.) There are present C—H···π-electron ring interactions in the structure (Tab. 1), too.

Experimental top

Mono(oxazoline) (0.5 g, 2 mmol) dissolved in 10 ml of tetrahydrofuran was placed into a two-neck 50 ml round-bottom flask that had been previously dried and that was equipped with a magnetic stirrer and a nitrogen inlet. The solution was cooled to 273 K and phenylmagnesium bromide (1.4 g, 8 mmol) which had been dissolved in 2 ml of tetrahydrofuran was added dropwise under nitrogen atmosphere to the solution of monoxazoline in tetrahydrofuran. The reaction mixture was stirred for 2 h at the same temperature. Then thin layer chromatography showed that the raw material had disappeared and indicated completion of the reaction. In the following step, 15 ml of saturated NH4Cl was added into the reaction solution at 273 K. The product was extracted by ethyl acetate (3×10 ml). The combined ethyl acetate extracts were dried over Na2SO4. The residue obtained after the evaporation of the solvent was purified by silica gel column chromatography with petroleum ether. The crude product was dissolved in 1 ml petroleum ether and the crystals were recrystallized after 4 hours in 55% yield as white or colourless needles typically 2-3 mm long and 0.5 mm wide. Melting point: 380-381 K (determined by a X-4 digital display microscopic melting-point apparatus).

Refinement top

The H atoms which have not been involved in the disordered phenyl rings were discernible in the difference electron density maps. The H atoms which were attached to the carbons were situated into the idealized positions and constrained using the following constraints: Caryl—Haryl = 0.93; Cmethyl—Hmethyl = 0.96; Cmethylene—Hmethylene = 0.97; Cmethine—Hmethine = 0.98 Å. UisoHaryl = 1.2UeqCaryl; UisoHmethyl = 1.5UeqCmethyl; UisoHmethylene = 1.2UeqCmethylene; UisoHmethine = 1.2UeqCmethine. The positional parameters of the hydroxyl hydrogen were freely refined while UisoHhydroxyl = 1.5UeqOhydroxyl. The occupational parameters of the disoredered phenyl rings were constrained in such a way that the their sum equalled to 1. The displacement parameters of the corresponding disordered atoms C21a, C21b ··· C25a, C25b were restrained by the command ISOR 0.01 0.02 and SIMU_* (SHELXL97, Sheldrick, 2008). In absence of significant resonant scatterers 1284 Friedel pairs have been merged by application of the command MERG 3 [SHELXL97 (Sheldrick, 2008)].

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
